Cleanroom Air Showers
Cleanroom Air Showers
Esco Air Showers (EAS) are self-contained chambers installed strategically at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space to mitigate the risk for cross-contamination.
Personnel and materials entering or exiting the controlled environment are “scrubbed” with ULPA-filtered air by high-velocity air jets running at 18-30 m/s (3543-5906 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.
Esco is the pioneering company for the manufacture and construction of cleanroom air showers with
different applications in the following areas:
- micro-electronics
- semiconductors
- pharmaceutical
- spray painting
- laboratory animal research
- food markets
With greater than 40 years of experience in the industry, Esco is consistently manufacturing, and supplying reliable air showers and clean air solutions to reduce the potential for cross-contamination, and enhance cleanroom integrity.
Features
High-velocity air jets
High-velocity shower jets running at 18-30 m/s to ensure efficient scrubbing action to remove particulate matter
Stainless steel nozzles
Permanently lubricated direct drive centrifugal blowers used in conjunction with stainless steel air nozzles
Programmable operation
Operating modes can be programmed in the field
Reliable microprocessor control system
Microprocessor controller supervises all functions
ULPA filtration
The typical efficiency of ULPA filter is > 99.9995% at 0.3 micron particles.
Pre-filtration
A disposable prefilter with 85% arrestance extends the life of the main filter.
Emergency buttons
An emergency stop button is mounted on both sides of the shower
Indicator lights to signal door status
Indicator lights mounted on both sides of the exterior of the air shower to regulate traffic flow, in and out of the cleanroom.
Durable doors
Heavy-duty, durable doors with glass windows to permit visibility.
Powder-coated steel construction
The air shower is constructed of electrogalvanized steel sheets with an abrasion-resistant oven-baked powder coated finish. (Optional: Stainless steel 304 construction)
Uniform lighting
Light diffusers ensure uniform lighting throughout the chamber
Principle
- Air is forced by the blower(s) through ULPA filter(s) which are 99.9995% efficient against particles of 0.3 microns.
- Filtered air is ejected through nozzles at high velocities into the chamber. These turbulent air streams disperse particulate matter on all surfaces.
- Dispersed particulate matter migrate with the air stream towards the lower areas in the air shower chamber. Air enters the blower supply plenum through pre-filter(s) installed at the base of the chamber.
- The air is continuously filtered and recirculated. The air shower is a self-contained device and does not exchange air with the environment it is placed in.
